To all whom it may concern .Be it known that L Jones 'a citizen of theUnited Stet-r Los Angeles, in the count geles, tote of California.invented new and useful Improvements in Andi solo ing Means for. iiutoniobiles. of which the following is a specification;

This invention relates to a locking device for a gasolene engine of anautonwbilc gasolene motors used for other anrposes.

The object is to prevent starting or open 1 ll El V 3 to avoid removalor theft of an nutomchi Further objects and advantages of t inventionwill be hronghtout in the specifications. I

Referring to the drawings, Figure 1 shows a front elevation of thelocking levice and causing. Fig. 2 shows a plan view of the de- ,viceand a. perforated air muzzle attached, also a small section of thecasing cut away to show means of securing the loclr into t casing.

. Referring to the parts in detail; this invention provides an efiectivemeans adapted to admit air under control of lock into the gas supply ofan engine; its purpose is to prevent the removal 01. an automobile by anunauthorized person the device is further ndaptnhle for admitting"variable quantities of air into the vapor to reduce its richness forsmoother orking and economy. The main object of the invention is toprovide simple means adapted to prevent the removal of an automobile,which is accomplished by removal of the key 3, from the lock 2. 'ThisWill move the valve 6 by the'lever which is attached to the look, fromits seat and. leave a. full opening to the valve outlet into tube 8 andinto gas manifold 29; the key is then removed and the valve is therebyleft open.

The key may come i in. the lo- \vhenthe valveclosed \vhi in this position if hey turned in the reverse direction itwill open. the volvin ropon tion to movement of the key, thus by turningthe key slowly, to a, point that will supply much as desired, in thismanner the device can he iised. for mnplyinp; air I01" a. lean mixtureof Further reference to the numbers connect ed with the diiierentfigures; 1 is a casing. preferably a (lie custinq. In assembling thedevice, the valve 6 carrying a spring 12 is placed in recess 23, thisvalve is placed and seated in casino; 1 before lock '2 is installed. Thespring 12 is intended to hold the valve steady. 2 ldesignntes a rib orit may he a. recess to permit of inserting a flexible or other kind ofmaterial if desired. T is an Casing l, is provided with an air inlet14:, also provided with a perforated inuzzled inlet 13. The flange 16 isprovided with air spaces around its face and outer edge in the form ofgrooves 15: nod 2'2 is intended to hold valve 6 from displacement. Thelock 2 is installed in the casing l and held in place by pin 19, on theback of this lock is a. member 5. which is secured to inder i of the.look. When key 3 is inserted and to the right or left. the key willrotate the cylindr l accordingly and as member 5 is secured to thiscylinder it me; be moved in either direction; for instanc.

Wl'ien the valve is openand the engine rotating air will rush through the air vents 14 and 15and perforated muzzle 13 into casing 1 and out through pipe 8 into themanifold and thus prevent the engine operating. The perforated muzzle13, also air vents 15 and inlet i iare of much importance and areprovided and arranged as shown to make it a difficult matter to stopthem up, as in such an event, valve 6 would not signify I, much since aliberal amount of air is re- There a variety of known valves and manyways of operating them, and which could be used with some modificationin working out a similar improvement. to the applicants device givingsubstantially the a same result and under control of locking meansassociated with the key of the lock,

' for instance, a ball valve, a rotary valve,

able parts associated with the lock are ar-' ranged and made adaptablefor moving the valve to and from the valve seat, any such combinationhaving locking means and the inner parts associated with and moved bythe loci: vl applied to a gasolene motor for supply: air, comes withinthe scope of the applic s invention.
